ABSTRACT

The present application provides a hetero-cyclic compound capable of greatly enhancing a lifetime, efficiency, electrochemical stability and thermal stability of an organic light emitting device, and an organic light emitting device containing the hetero-cyclic compound in an organic compound layer.

TECHNICAL FIELD

This application claims priority to and the benefits of Korean Patent Application No. 10-2016-0179082, filed with the Korean Intellectual Property Office on Dec. 26, 2016, the entire contents of which are incorporated herein by reference.

The present application relates to a hetero-cyclic compound and an organic light emitting device using the same.

BACKGROUND ART

An electroluminescent device is one type of self-emissive display devices, and has an advantage of having a wide viewing angle, and a high response speed as well as having an excellent contrast.

An organic light emitting device has a structure disposing an organic thin film between two electrodes. When a voltage is applied to an organic light emitting device having such a structure, electrons and holes injected from the two electrodes bind and pair in the organic thin film, and light emits as these annihilate. The organic thin film may be formed in a single layer or a multilayer as necessary.

A material of the organic thin film may have a light emitting function as necessary. For example, as a material of the organic thin film, compounds capable of forming a light emitting layer themselves may be used alone, or compounds capable of performing a role of a host or a dopant of a host-dopant-based light emitting layer may also be used. In addition thereto, compounds capable of performing roles of hole injection, hole transfer, electron blocking, hole blocking, electron transfer, electron injection and the like may also be used as a material of the organic thin film.

Development of an organic thin film material has been continuously required for enhancing performance, lifetime or efficiency of an organic light emitting device.

Experimental Example Experimental Example 1

1) Manufacture of Organic Light Emitting Device

A glass substrate on which ITO was coated as a thin film to a thickness of 1500 Å was cleaned with distilled water ultrasonic waves. After the cleaning with distilled water was finished, the substrate was ultrasonic cleaned with solvents such as acetone, methanol and isopropyl alcohol, then dried, and UVO treatment was carried out for 5 minutes in a UV cleaner using UV. After that, the substrate was transferred to a plasma cleaner (PT), and plasma treatment was carried out under vacuum for ITO work function and remaining film removal, and the substrate was transferred to a thermal deposition apparatus for organic deposition.

On the transparent ITO electrode (anode), organic materials were formed in a two-stack white organic light emitting device (WOLED) structure. As for the first stack, a hole transfer layer was formed first by thermal vacuum depositing TAPC to a thickness of 300 Å. After forming the hole transfer layer, a light emitting layer was thermal vacuum deposited thereon as follows. The light emitting layer was deposited to 300 Å by doping FIrpic in 8% as a blue phosphorescent dopant to TCzl, a host. An electron transfer layer was formed to 400 Å using TmPyPB, and then a charge generation layer was formed to 100 Å by doping Cs₂CO₃ in 20% to a compound described in the following Table 3.

As for the second stack, a hole injection layer was formed first by thermal vacuum depositing MoO₃ to a thickness of 50 Å. A hole transfer layer, a common layer, was formed by doping MoO₃ to TAPC in 20% and forming to 100 Å, and then depositing TAPC to 300 Å. After depositing a light emitting layer to 300 Å thereon by doping Ir(ppy)₃, a green phosphorescent dopant, in 8% to TCzl, a host, an electron transfer layer was formed to 600 Å using TmPyPB. Lastly, an electron injection layer was formed on the electron transfer layer by depositing lithium fluoride (LiF) to a thickness of 10 Å, and then a cathode was formed on the electron injection layer by depositing an aluminum (Al) cathode to a thickness of 1,200 Å to manufacture an organic light emitting device.

Meanwhile, all the organic compounds required to manufacture the OLED device were vacuum sublimation purified under 10⁻⁶ torr to 10⁻⁸ torr by each material to be used in the OLED manufacture.

As shown from the results of Table 3, the organic light emitting devices using the charge generation layer material of the 2-stack white organic light emitting device of the present disclosure had a low driving voltage and improved light emission efficiency compared to Comparative Examples 1. Particularly, it was identified that Compounds 1-1, 1-6, 1-26, 3-10, 4-1, 4-5, 6-10, 6-14, 7-5, 8-39, 9-5, 10-5, 12-5, 13-2, 13-5, 13-13, 13-18, 13-19 were significantly excellent in all of driving, efficiency and lifetime.

The presumed reason for such results is that the compound of the present disclosure used as an N-type charge generation layer formed with an invented skeleton having proper length, strength and flat property and a proper hetero-compound capable of binding with metals is doped with an alkali metal or an alkali-earth metal to form a gap state within the N-type charge generation layer, and electrons produced from a P-type charge generation layer are readily injected to the electron transfer layer through the gap state produced within the N-type charge generation layer. Accordingly, the P-type charge generation layer favorably carried out electron injection and electron transfer to the N-type charge generation layer, and as a result, it is considered that a driving voltage of the organic light emitting device decreased, and efficiency and lifetime were improved.

As shown from the results of Table 4, the organic light emitting devices using the charge generation layer material of the blue organic light emitting device of the present disclosure had a low driving voltage and improved light emission efficiency compared to Comparative Examples 2. Particularly, it was identified that Compounds 1-1, 1-6, 1-26, 3-10, 4-1, 4-5, 6-10, 6-14, 7-5, 8-39, 9-5, 10-5, 12-5, 13-2, 13-6, 13-9, 13-13, 13-14, 13-17, 13-21 were significantly excellent in all of driving, efficiency and lifetime.

The presumed reason for such results is that the compound of the present disclosure used as an N-type charge generation layer formed with an invented skeleton having proper length, strength and flat property and a proper hetero-compound capable of binding with metals is doped with an alkali metal or an alkali-earth metal to form a gap state within the N-type charge generation layer, and electrons produced from a P-type charge generation layer are readily injected to the electron transfer layer through the gap state produced within the N-type charge generation layer. Accordingly, the P-type charge generation layer favorably carried out electron injection and electron transfer to the N-type charge generation layer, and as a result, it is considered that a driving voltage of the organic light emitting device decreased, and efficiency and lifetime were improved.
